Saturday update:
GILFORD, N.H. – A teen is deceased, and a death investigation is underway at Lake Winnipesaukee in Gilford.

At 12:48 p.m. on Friday, June 20, 2025, the New Hampshire State Police (NHSP) – Marine Patrol received a 9-1-1 call reporting a person had gone into the water and failed to resurface in Lake Winnipesaukee. The incident occurred in the area known as the “Broads,” near Diamond and Rattlesnake Islands.

Marine Patrol officers responded and located a boat with three women on board. They reported that a 17-year-old boy entered the water to recover a bag that had fallen overboard and, due to rough water conditions caused by strong winds, the teen appeared to struggle to swim, eventually submerged, and did not resurface.

An initial search was conducted by members of Marine Patrol, the Gilford Fire Department, and the Alton Fire Department, but the teen was unable to be located. The New Hampshire Fish & Game Dive Unit was called to assist with the search, and at 7:02 p.m., the dive team found and recovered the teen’s body.

The name of the teenage victim is being withheld. An autopsy has been scheduled.

Marine Patrol was also assisted by members of the Gilford Police Department.

The initial investigation indicated this was a drowning. All aspects of the incident remain under investigation. Anyone with information that may assist the investigation is asked to contact Sgt. Seth Alie of Marine Patrol at Seth.P.Alie@dos.nh.gov or 603-227-2117.
